Multiple ComposerClassLoaders

This is part of the larger issue that the way composer works out of the box (or the way we try to use it with drupal) is fundamentally broken. There is an issue in libraries project queue with discussion on how to fix things properly.

I am not sure if there is a simple workaround we can introduce to make this better.

Composer protects against this issue by appending a suffix to the ComposerAutoloaderInit class during generation. PHP's autoloader loads the first Composer ClassLoader class it finds so it doesn't load the file twice.

Needing something that would work for D7 I have created the following module:
